Task# Fizzy Juice

Illustrative MathematicsVaries

The goal of this task is to provide an engaging context for students to work with ratios. If orange juice and soda are available, it would be interesting to have students test the mixtures described in the problem (ideally in a 'blind' taste test) to see if they can taste a difference: note that even if the volumes are poured and measured accurately, the ratios chosen are close enough that it might not be possible to taste the difference. This task is designed to elicit a variety of student responses. If given at the beginning of the unit, students will likely reason directly with the numbers, as in the fifth provided solution.
